PAPER BOTTLE.

Specification 'ofLetters Patent.

Application filed February 21, 1919. serialia.'a'zaase.

To all whom it may concern:

Be it known that I, GEORGE R. Iu NN, a citizen of the United States,resldmg at Baltimore, in the State of Maryland, have invented a new anduseful Paper Bottle, of

which the following is a specification.

. ferred forms of This invention relates to paper bottles and one of itsobjects is to provide a container of this character having end closuresall portions of which are located entirely within the walls of-thecontainer so that a number of the containers can be packed in a cartonwhich would be too small to hold a like, num-v ber of containers of thesame capacity having caps extending around or housing the ends ofthecontainers.

A further object is to provide a container utilizing flat abutments orshoulders consti-.

Another obJect is to provide novel means for locking the caps inposition. With the foregoing andother objects in view which will appearas the description proceeds, the mvention consists of certain noveldetails of construction and combinations of parts which will behereinafter more fully described and pointed out in the'claims it beingunderstood that various changes may bemade in the proportions andarrangements of the parts without departing from the spirit orsacrificing any of the advantages of the invention as set forth in theappended claims.

In the accompanying drawings the prethe invention have been shown. i

In said draWings- Figure 1 is .a view partly in section and partly inelevation of a paper bottle embodying the present improvements.

Fig. 2 is an enlarged section through a portion of one cap and'showingthe means for detachably securing it 'infplace.

Fig. 3 is an enlarged section through a portion of a container andshowing a modified means for securing thecap in position.

' Referring to the figures by characters of reference, 1 is apapercontaine'r stiffened or Patented Sept. 9,1919.

reinforced wherever desired by ribs 2 pressed thereinto.

tainer and each is preferably formed with its outer face flat, as at 5,thus to present a flat shoulder or seat for the end closure of thecontainer. These fiat shoulders, 5, are perpendicular to the axis of thecontainer thereby to stiffen the container against pressure along radiallines.

Each closure includes a paper disk 6 so proportioned as to fit snuglywithin one end portion of the container and to rest upon the shoulder 5,said disk having a flange 7 adapted to fit against the inner surfaceofthe wall of the closure and to be supported Stop ribs '3 and 4 are ipressed into the end portions of the conwith its free edge flush withthe end of the closure.

For the purpose of stiffening the flange of the closure atone end of thecontainer, parallel rooves 8 are pressed into the inner facet ereof,these grooves also constituting means for facilitatingv the removal ofthe closure as hereinafter pointed out. These grooves serve to keep theclosure in shape rior to its insertion into the container. he closure inthe other end of the container and which constitutes the bottom of thedevice isnot to be removably mounted. Instead it can be held in place bya suitable araflin, or the like, as shown in adhesive, Fig. l or, ifpreferred and as shown in Fig. 3, an annular groove 9 can be pressedinto the flange 'of the bottom closure so that said closure can besnapped into place to bring the rib a into the groove. In either casethe connection between the container and the bottom cap is sealed byplacing the lower end of the container .in a film of melted paraflinthus to leave a thin layer of the paraffin upon the bottom edges of thecontainer and its bottom closure as shown at 1Q. After thecontainer hasbeen filled With a liquid, powder, or other material, the top closure isinserted thereinto so as to become seated snugly upon the shoulder ofthe rib 3. By the use of a hand unch or other dcv1ce,.

incisions are made in t e contacting port-ions of the flange 7 and thecontainer wall so as to produce outwardly and upwardly inclined lockingtongues or barbs 11 each. made up of the two thicknesses of'materia-l.The thick:

ness cut from the flange 7 will be pressed out into the opening formedin the wall of the container, as shown clearly in Fig. 2. Thus it willbe seen that by perforating theflange of the cap and the container atintervals, the cap will be locked securely in position. The cap can beunlocked, however, by pressing the tongues inwardly until they lie flushwith the faces of the flange and container wall and fill the openings.By then placing a finger nail in one of the grooves 8 the cap can bepulled out of the container and the contents removed.

If desired, and as shown in Figs. 1 and 2 the top of the container canbe sealed by standing the closed container in an inverted positionwithin a film of hot paratlin thus to form a thin layer of paraliin uponthe edge of the container and the flange of its cap, as shown at 12.Also, if desired, a small amount of paraflin can be placed in theopenings where the tongues 11 are located, thus to close the openingsand likewise prevent the tongues from being pressed back into theopenings while the container is being handled. However under ordinarycircum- .stifi'enin" face )er )endicular to the axis of the container,and a closure insertible into the container and Into engagement withsaid face. 7

2. The combination with a paper container, of a. stitfening rib pressedthereinto, a flanged paper closure insertible into the container andinto engagement with the rib, there being annular grooves pressed intothe inner surface of the flange of the closure for holding the closurein shape prior to insertion.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature in the presence of two witnesses.
